Abstract (en)
An ink cartridge includes a main body and a cover. A liquid storing chamber and an air introducing post for communicating the liquid storing chamber with the outside atmosphere are disposed in the main body. A liquid filling port is disposed on the cover. A balancing chamber, a detecting chamber, and a floater are disposed in the main body. The balancing chamber and the detecting chamber are in communication with each other via a through hole. The detecting chamber and the liquid storing chamber are in communication with each other via a liquid guiding port. The floater, whose density is lower than that of the ink liquid, is located in the detecting chamber. The lower portion of the air introducing post communicates with the outside atmosphere via a waterproof sponge. The ink cartridge may conveniently monitor usage of ink liquid in the main body and reduce residual ink.
